3M™ SelfCheck™ Automated Library System, the first commercial automatic book check-out system, is delivered by 3M.

The system helps libraries to better track books and prevent theft.

The first bus is built that is powered by a fuel cell.

A fuel cell converts the chemical energy from a fuel, such as hydrogen, into electricity when it comes into contact with oxygen. Cities around the world begin to use this technology for their public bus systems. In 1998, Daimler Benz and Toyota will launch prototype fuel-cell cars.

3M moves toward “green” products with Scotch-Brite® Never Rust™ Wool Soap Pads made with recycled materials.

3M also added Scotch-Brite® High-Performance Cleaning Cloths made of biodegradable bamboo.
